Prothane 6-316

Clunky Ride?

As the owner of a newer model Ford Mustang you are most likely going to drive fast. Well, as you fly around in your Mustang you may begin to notice that taking corners doesn't feel the same. In addition, you may occasionally hear a clunking noise underneath your vehicle. These noises may be caused by a loose control arm. The OE rubber bushings used in the initial construction of your Mustang are prone to warping and wearing out, leaving your control arm room to shift. This results in metal-on-metal contact with your chassis, misalignment, and loosened steering around corners. A common issue with replacing these bushings is that there are no bushings sold separately from the factory, leaving technicians with no choice but to install a new set of complete control arms. Here at DST we know how important it is to get your Mustang running smoothly again, without breaking your bank. Luckily, Prothane has created the part for you!

The 6-316 Solution

With Prothane's 6-316 Rear Control Arm Bushings you can replace the worn out rubber OE bushings with much more durable polyurethane, without having to pay for entire control arms. The 6-316 comes with all four bushings you will need to cover both of your rear control arms. Not only is the polyurethane more durable than the stock rubber, but it also tightens up the suspension allowing for faster and smoother responses from your Mustang. For the misalignment problems, 6-316 is designed to maintain the alignment of your Mustang at the time of installation. So in order to get the most out of the 6-316 be sure to get your Mustang aligned right after installation.

Lifetime Warranty

The 6-316 Rear Control Arm Bushings come in either black or red. There is no material difference between the two, only the color changes. All of Prothane's parts are covered with a lifetime warranty handled in-house right here at DST.

Color

Prothane Red vs Black

Black, or Red? Red, or Black?

Prothane makes bushings in both colors. But is there a difference in them? Is one harder than the other? There are a lot of misconceptions about the color difference in Prothane's bushings, so let us at DST clear that up for you.

How are these two colors different?

Aside from the actual color, there isn't really a difference at all between the red and the black. They are the same durometer, or hardness, so they will perform the same and both should last the life of your vehicle.

What about the graphite rumor?

The black bushings do have a small amount of graphite mixed in with the polyurethane which has the potential to help with squeaking. But really, the best way to prevent Prothane bushings from squeaking is to use the supplied pre-lube* and grease them properly at install. So whether you choose the red, or the black, just be sure to grease them properly to avoid any squeaking.

* Some types of bushings only compress, such as body mounts and endlinks, and do not come with grease because they do not need grease. So if your kit comes with grease, be sure to use it!
